Question

In each of the following numbers, replace M by the smallest whole number to make the resulting number divisible by 11.
(1) 39 M 2
(i) 3 M 422
(ii) 70975 M
(iv) 14 M 75 ​

Answer 1

Answer:

1) Replacing M by 8- 3982

2) Replacing M by 7- 37422

3) Replacing M by 3- 709753

4) Replacing M by 5- 14575

Step-by-step explanation:

The divisibility by 11 rule states that if the difference between the sum of the digits at the odd and even places equals 0 or divisible by 11, then the number is divisible by 11.

1) 3982

3-9+8-2= 0

2) 37422

3-7+4-2+2= 0

3) 709753

7-0+9-7+5-3= 21-10= 11

4) 14575

1-4+5-7+5= 0
